“…Then Fan et al used this method in fabricating large‐area MAPbI 3 thin films (100 cm 2 ) which was dense, uniform, and smooth, and the resulting device PCE could up to 7.73% (0.12 cm 2 area). [ 185 ] In total, SSPVD is also a promising candidate for the scale‐up of PSCs, which need to be further developed in the future.…”

As an emerging sunlight‐harvesting material, halide perovskite has obtained extensive achievements on device efficiency and stability in the past decade. Especially, the efficiency of lab‐scale perovskite solar cells (PSCs, 25.2%) is already comparable with that of crystalline silicon solar cells. However, the development of large‐scale perovskite solar modules is far behind small area devices due to difficult fabrication process and stringent requirements for film quality, the Achilles’ heel to hinder their commercialization. Therefore, the coating techniques of perovskite modules need to be developed and optimized continuously. Moreover, the underlying mechanism along with these coating processes should be revealed urgently. Herein, the recent advances for several popular coating methods are systematically summarized that are widely applied in the deposition of large‐scale films. The relevant mechanistic study, including the formation of wet film, and subsequent nucleation and growth kinetics during coating process, are discussed. The main target is to gain insight into the large‐scale PSCs fabrication. Hopefully, useful guidance is provided to further improvement of efficiency and stability of PSCs, which finally promotes their commercialization.

“…Related researches mainly focused on the scalable deposition methods and morphology modulation for high‐quality pinhole‐free perovskite layers. Various scalable deposition methods have been developed, including solution‐based methods (e.g., spin coating, [ 9 ] blade coating, [ 10 ] slot‐die coating, [ 11 ] bar coating, [ 12,13 ] spray coating, [ 14 ] inkjet printing, [ 4,15 ] screen printing [ 16 ] ) and vapor‐based methods (e.g., physical vapor deposition (PVD), [ 17 ] chemical vapor deposition (CVD) [ 18 ] ). Meanwhile, morphology control strategies including solvent engineering, [ 19,20 ] composition engineering, [ 21–23 ] and crystallization process control [ 24–26 ] have also been used to improve the quality of perovskite layers.…”

Power conversion efficiency of perovskite solar cells (PSCs) has been boosted to 25.5% among the highest efficiency for single‐junction solar cells, making PSCs extremely promising to realize industrial production and commercialization. Scaling up PSCs to fabricate efficient perovskite solar modules (PSMs) is the fundamental for applications. Here, present progresses on scaling up PSCs are reviewed. The structure design for PSMs is discussed. Various scalable methods and related morphology control strategies for large‐area uniform perovskite films are summarized. Potential charge transport materials and electrode materials together with their scalable methods for low‐cost, efficient, and stable PSMs are also summarized. Besides, current attempts on encapsulation for improving stability and reducing lead leakage are introduced, and the calculated cost and environment influence of PSMs are also outlined.

“…The easy deviation from the stoichiometric ratio directly leads to a decrease in film quality and repeatability 22 . To our knowledge, single-source thermal evaporation is a effective method for preparing large-area, high-efficiency perovskite solar cells 23 . In this study, 2D perovskite (BA) 2 (MA) 3 Pb 4 I 13 thin film was prepared by single-source thermal evaporation, and the effects of solvent annealing on the microstructural and optoelectronic properties of the thin film were investigated.…”

Hybrid two-dimensional (2D) halide perovskites has been widely studied due to its potential application for high performance perovskite solar cells. Understanding the relationship between microstructural and opto-electronic properties is very important for fabricating high-performance 2D perovskite solar cell. In this work, the effect of solvent annealing on grain growth was investigated to enhance the efficiency of photovoltaic devices with 2D perovskite films based on (BA)2(MA)3Pb4I13 prepared by single-source thermal evaporation. Results show that solvent annealing with the introduction of solvent vapor can effectively enhance the crystallization of the (BA)2(MA)3Pb4I13 thin films and produce denser, larger-crystal grains. The thin films also display a favorable band gap of 1.896 eV, which benefits for increasing the charge-diffusion lengths. The solvent-annealed (BA)2(MA)3Pb4I13 thin-film solar cell prepared by single-source thermal evaporation shows an efficiency range of 2.54–4.67%. Thus, the proposed method can be used to prepare efficient large-area 2D perovskite solar cells.
